  • Change the $domain variable to whichever domain you wish to query. Works with the majority of whois info; for some that won't, you may have to compromise: domain=google.com; for a in $(whois $domain | grep "Domain servers in listed order:" --after 3 | grep -v "Domain servers in listed order:"); do echo ">>> Nameservers for $domain from $a Note that this doesn't work as well as the first one; if they have more than 3 nameservers, it won't hit them all. As the summary states, this can be useful for making sure the whois nameservers for a domain match the nameserver records (NS records) from the nameservers themselves. Show Sample Output

    domain=google.com; for ns in $(whois $domain | awk -F: '/Name Server/{print $2}'); do echo ">>> Nameservers for $domain from $a <<<"; dig @$ns $domain ns +short; echo; done;

  • Mostly for Norwegians, but easily adoptable to others. Very handy if you are brainstorming for a new domainname. Will only display the available ones.. You can usually do this better with dig, but if you dont have dig, or the TLD only have an online service to check with, this will be usefull.. Show Sample Output

    check_dns_no() { for i in $* ; do if `wget -O - -q http://www.norid.no/domenenavnbaser/whois/?query=$i.no | grep "no match" &>/dev/null` ; then echo $i.no "available" ; fi ; sleep 1 ;done }

  • Strips the non-ip information from the dig output. Could be combined with "head -1" to ensure a single ip is returned. Useful for outputting as a variable for use in scripts. Show Sample Output

What Others Think

What's wrong with the current domain? It's to the point, and not some stupid hack to get a mediocre domain due to the good ones being taken.

I agree - I prefer the longer domain to cmdfu.com. I didn't know you could get a .fu TLD though.

Sadly, there is no .fu domains: http://www.iana.org/domains/root/db
